Aphids can vector cucumber mosaic virus (CMV), which causes serious damage to many crops. Snap-bean crops in Pennsylvania began to show CMV-like symptoms in 2003, which coincided with the appearance of Aphis glycines, the soybean aphid. We investigated the species composition of aphids in snap bean fields along a valley transect in central Pennsylvania and related that to the transmission efficiency of the most prevalent species. Species composition was determined by trapping aphids in six fields in Centre County over a 3 year period. The soybean aphid was one of the more prevalent species, and is an efficient vector of CMV. To further understand the lifecycle of the soybean aphid in Pennsylvania we estimated the prevalence of its primary host, Rhamnus cathartica (common buckthorn), in the wooded areas surrounding the valley.

    Hi Amanda Bachmann, I unfortunately did not have the opportunity to see your poster at the ESA meeting in December, but I noticed I am doing similar experiments with snap bean here in Wisconsin. I was just wondering what other aphid species you were catching in bean and how did you determine transmission efficiencies? I was thinking of doing some transmission assays with soybean aphid and snap bean, but if those have already been done for CMV, WONDERFUL! I could greatfully move on to some of the other viruses we're seeing here. Any information you would be willing to share would be greatly appreciated. Thank you, Emily
